Von Schweikert speakers are notorious for having many generation updates year after year, (until each model is discontinued or completely revised). This has me wondering if each model is a "work in progress" , for the consumer to buy, as the development has yet to be finished into a refined product. Everyone I have known who has bought Vons has eventually replaced them with other, more established brands (Dunlavy, Aerial and Proac in each my freinds cases). If you decide to buy them, make sure that you check the used market first. Last year, when one of my buddiesy tried to sell his Vr4's, he was competing against 14 others that were also for sale! (He ended up getting a fraction of what he wanted) One thing is for sure, Von Schweikert speakers do not hold their value.
